Now I understand the reason for the "extra" table entries, I was
thinking that the jump table solution would be the smallest, so I didn't
think there was any likely code size improvement. But using
-fno-jump-tables option does make the code very slightly smaller in my
case (just 4 bytes).
I think it would be helpful in future versions if the compiler could
output a separate table and name it, like it does for PROGMEM tables.
Then it's clear what's in each table. Is that possible?

Sorry. I has not understood your phrase.
If you consider that the "jump table" optimisation is not effective for your project, you can
disable it with the "-fno-jump-tables" switch. The target specific switch
"-mno-tablejump" should be removed from GCC 4.5.
Anatoly.
